Help with nutrition ?

Hello !

I have a big dilemma and that is the diet ! I'm a 17 year old student who has no freaking idea on what type of diet to do. (I'm really skinny) The primary purpose of this diet is for muscle gain, but what is a good diet ? I'm asking your help to establish a ''menu'' of the day ! Thanks a lot, this counts to me.

I can tell you what my diet is because it works preety good on me.
breakfast 7am eggs/milk/tea w bread and cheese
snack 9am : glass of milk and some fruit
lunch 11am : soup and a steak/vegetables/omlette/cabbage
snack 2pm : 2 slices of bread with some cheese and salamy or pork
dinner 7pm : mainly vegetables or steaks
snack 8:30 pm : glass of milk and some fruit
10pm : glass of milk/oat with yogurt

This menu works great. Hope it helped
